There are 8 different isometric classes (45 minute session) and 3 HIIT classes (15 minute session) you can sign up for. They also have the FX zone which is where a smith machine, dumbbells, and kettlebells are to do weight lifting as well. The classes are in little saunas and they can hold up to 3 people, although I will say most of the time you are able to get a room to yourself. The door is always locked, but members have access to open the door 24/7 to workout so it is super safe! The place is always clean and the staff are so friendly! They have a vending machine with lots of protein snacks and water that is always stocked. Not to mention the other people that work out there are awesome too! I have been going for 7 months and have loved it!

I'm one of the few people in Missouri privileged with the opportunity to try the elite ARX machine…read moreat Biofit, and it left me truly amazed that I have had the honor of experiencing something that's going to change history and how people experience finding and building their own strength. This is a long review but every bit of it is necessary because this needs to be known, shared, and experienced!!! This exercise equipment has created a new neural pathway for me and how I now view exercise, my time spent at the gym and my ability to reach peak levels endurance. As a fitness enthusiast who's tried everything from P90X to Peloton, nothing compares to this experience. I love lifting free weights and unlike most people I don't count my reps per se I count my length of time doing each rep, which is the TUT method (time under tension). Most workout fanatics may use this method because it's so beneficial. Time under tension is the duration a muscle is under strain during exercise. It focuses on the time spent in each movement to enhance muscle growth and endurance. For me, this is the best and fastest way to tone up, get great blood flow to muscles (pump), and see results. What I now know is ARX eclipses the TUT method and any other machine out there. Now the tut method is great but even though you're holding that tension there's nothing but gravity working against you and your own strength which is great but be honest how hard to you really push yourself at the gym? With this state-of-the-art equipment, the machine is working against you via resistance BUT is also working for you. It's as if it's working every muscle everywhere all at once!! It somehow knows what limit to push your body to so you get the perfect amount of resistance, which in turn gives you the metrics of your own strength. Something lifting has never gauged for me better yet has never resisted against me to enhance my strength. ARX is so mind-boggling that talking about it doesn't do it justice--you must experience it in person! No matter what your strength level is, this machine will match you and make you work smarter, not harder, plus you can get a full-body workout in 10-15 minutes. My first time was less than 5 minutes on one machine and it was a leg press. I was in my casual everyday clothes. I wasn't wearing tennis shoes I was wearing heels jeans and a leather jacket! Why? I went in for a quick demo thinking it would be demonstrated for me by the owner. Nope watching would not have done me any good because you don't know the might of this machine until you experience it. So it bears repeating I was in high heels, and I was still able to accomplish a magnificent burn, experience a life transforming piece of equipment and more importantly I didn't have to take my shoes off and I didn't break a heel! Now, my second time was less than 10 minutes and was a full-body workout. This time I had on gym attire and tennis shoes were a must because after the experience the week before I wanted to see what I could really accomplish without worrying about snapping a heel off. At the end of my short session, I felt as if I had been working out for 45 minutes. I only used three machines and didn't lift a single weight!! My muscles were so taxed I couldn't complete my usual HIIT routine on the self powered treadmill, and in all honesty, that routine may become a thing of the past, along with my typical gym membership. These slick pieces of machinery will end up making typical gym equipment obsolete simply due to the science and metrics behind it. Plus, it's designed to give you one of the most efficient methods of working out, which is time under tension. The ARX is literally based on Time Under Tension (TUT) plus it tracks your strength metrics, tailors resistance to your personal limits, takes less than 10 minutes, and you can get results by using it once or twice a week!! I value my time very much, and being able to cut down my commute to and from the gym, the time in between sets, and the time to perform my workout is a win-win for me. It was an unparalleled workout experience. It's hands down the most amazing workout I've ever had! Talking about this is not the same as experiencing it. You MUST experience it then see how you feel the day after. I promise you'll want to go back and try beating your own scores again!
